Zero Tillage — Complete Guide for Indian Farmers

Cause

Uneven residue spread or a drill set too shallow for the stubble load left seed exposed or too deep.

Fix

Re-check drill depth on a short test pass and adjust down-pressure before continuing.

Prevention

Always start with a 10–15 metre test strip and walk it before drilling the full field.

Cause

No tillage means weed seed near the surface germinates instead of being buried.

Fix

Use a pre-emergence herbicide suited to zero-till wheat within 48 hours of sowing.

Prevention

Weed pressure typically drops from year two once residue mulch builds up and shades out early flushes.

Cause

Retained residue gives rodents more cover right at the field edge.

Fix

Place zinc phosphide bait stations along field bunds before sowing, following label directions.

Prevention

Keep field edges and bunds clear of loose residue piles where rodents nest.

Cause

Residue load exceeds what the drill's furrow openers are rated to cut through cleanly.

Fix

Switch to a Happy Seeder, which is built for standing and heavy loose residue, or reduce forward speed.

Prevention

Match the machine to the residue load before the season, not mid-field.

Zero tillage (also called no-till or direct drilling) sows the next crop straight into the previous crop's stubble, with no ploughing, harrowing or planking in between. A zero-till drill or Happy Seeder cuts through residue, places seed and fertiliser, and closes the slot in one pass.

Typically ₹2,500–₹3,500 per hectare on land preparation alone, plus roughly 50 litres of diesel. Counting the value of sowing 7–10 days earlier, the total swing on a wheat-after-paddy field regularly crosses ₹6,000/ha.

No. It works best for wheat sown after paddy or another cereal, and for maize, soybean and gram, which tolerate a firm, undisturbed seedbed. Potato and most root and tuber crops still need loose, worked soil and are a poor fit.

Most farmers do not own one. Zero-till drills and Happy Seeders are widely available on hire through Custom Hiring Centres and FPOs, usually for less per acre than the diesel and labour a conventional pass would cost.

No — done correctly it usually raises yield. The 7–10 days of earlier sowing that zero tillage buys is worth roughly 2–3 quintals a hectare on wheat, since late-sown wheat loses yield to terminal heat stress.

Weed pressure is often slightly higher in the first year or two, because tillage no longer buries surface weed seed. A pre-emergence herbicide applied within 48 hours of sowing controls this, and pressure typically eases as residue mulch builds up.

Yes — that is its main environmental purpose. Instead of burning paddy stubble to clear the field, zero tillage drills straight through it, so the residue stays on the field as mulch instead of going up in smoke.

A zero-till drill handles light to moderate loose residue. A Happy Seeder is built specifically for heavy standing paddy stubble that would choke a plain zero-till drill, and needs a Super SMS-fitted combine at harvest to spread residue evenly first.
